所以我得到了这段代码,我需要在或多或少的所有页面上重复使用,但我有点厌倦了更改一个页面并且必须在 10 个或更多地方做同样的事情,有没有什么更好的方法来做到这一点?
使用 Xamarin.Forms。也许可以使用自定义 Controller 或使用标记扩展在堆栈布局内部执行 x:static 引用的其他方式来执行此操作?

最佳答案
您可以创建一个 CustomView,然后将其包含在您的页面中。
为了实现这一点,您创建一个 YourCustomView.xaml,
<ContentView xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
x:Class="YourProject.YourCustomView">
</ContentView>
并且,在您的 Page.xaml 中包含它
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
xmlns:views="clr-namespace:YourProject;assembly=YourProject"
x:Class="YourProject.YourPage">
<views:YourCustomView/>
</ContentPage>
下一步是绑定(bind)您需要的属性,为此,您需要在 CustomView 中创建 BindableProperties。您可以在您想要的所有页面中重复使用它。
